This must be a new friendship. These two don't look like much of an item. It appears that the blog or pictures is trying to make more out of it than what is really there. Most of the pics were of them separate. The one or two shots that were of them together seemed innocent. More like a good friend than a romantic interest. She didn't even jet ski with him. She had her friend ride with her. The separation of Rhianna and Chris is still so new that it seems like right now she is just trying to get her feet wet again. Matt may truly be interested in Rhi, but her tragic breakup is still too recent for her to attempt a relationship right now. But on the up side she does look great!
